## Introduction

Write C program to find the sum of first and last digit of any number

#include <stdio.h> #include <stdlib.h> #include <math.h> int main(void) { int num, sum=0, firstDigit, lastDigit; printf("Enter any number: "); scanf("%d", &num); lastDigit = num % 10; firstDigit = num; while(num >= 10) { num = num / 10; } firstDigit = num; //Finding sum of first and last digit sum = firstDigit + lastDigit; printf("Sum of first and last digit: %d", sum); return 0; }
